Frequently Asked Questions

What is the difference between camelCase and snake_case?

camelCase joins words together with the first word lowercase and subsequent words capitalized (myVariableName), while snake_case separates words with underscores and keeps everything lowercase (my_variable_name). camelCase is common in JavaScript and Java, while snake_case is preferred in Python and Ruby.

When should I use kebab-case?

kebab-case (words-separated-by-hyphens) is ideal for URLs, CSS class names, and file names because it's URL-safe, easy to read, and widely supported. For example: 'my-awesome-blog-post' is better than 'My Awesome Blog Post' for a URL slug.

Is my text data secure when using this tool?

Yes, absolutely! All text conversion happens entirely in your browser using JavaScript. Your text is never sent to any server or stored anywhere. You can even use this tool offline once the page is loaded.

Can I convert text back and forth between different cases?

Yes! You can convert your text between any of the 7 supported formats as many times as you want. Simply click different format buttons to see your text in various cases instantly.

What happens to special characters and numbers?

Special characters and numbers are preserved during conversion. For programming cases (camelCase, snake_case, kebab-case), spaces and special characters are replaced with underscores or hyphens, while numbers remain unchanged.
